This interactive scatter plot visualizes nutritional data for McDonald’s menu items, sourced from a CSV hosted on VizHub. Users select which two nutritional attributes (e.g., Calories, Sodium) to compare using dropdown menus, while colored circles represent item categories (Beef, Chicken, etc.). A clickable color legend filters the data, and hovering over a circle reveals a tooltip with the item’s name, category, and values. Built with D3 v5, the visualization uses `scaleLinear`, `axisBottom`, `axisLeft`, and `transition()` for animated circle updates, with SVG rendering and interactive menus.
